Target restoration space (TRS) is the most precise space required for designing optimal prosthesis. TRS consists of an internal or external tooth space to confirm the esthetics and function of the final restoration. Therefore, assisted with quantitive analysis transfer, TRS quantitative analysis is a significant improvement for minimum tooth preparation. This article presents TRS quantity-related measurement, analysis, transfer, and internal relevance of three TR. classifications. Results reveal the close bond between precision and minimally invasive treatment. This study can be used to improve the comprehension and execution of precise esthetic prosthodontics.

The visual angle of active participation reference model was not scientific and its contents were not sys-tematic in the past EBM information service. A new EBM information service model was thus established by compa-ring the finding process of evidence and the transforming process ofinformation-knowledge-intelligence with the need of evidence-based decision making in clinicians as a logic starting point in order to provide the theory of what to do andhow to scientifically do for clinical librarians and clinicians, to effectively direct clinical librarians to perform EBM information service, and to help clinicians to scientifically make their decision.

Objective To investigate pathogens distribution and their drug resistance of hospital acquired pneumonia (HAP) in local elderly paraplegic patients,and to help to gain experience in early using antibiotics.Methods One hundred and thirty six elderly patients diagnosed as HAP from January 2007 to December 2010 in our hospital were selected.Pathogens distribution and their drug resistance were detected.Results One hundred and fifty two pathogens are isolated from the 136 patients,and most of them are gram negative bacteria which accounts for 70.4％.The first three pathogens are Klebsiella pneumonia(24.3％),Escherichia coli (20.4％) and Pseudomonas Aeruginosa (18.4％).Gram-positive cocci accounts for 25.0％ in total pathogens,among them,staphylococcus aureus and streptococcus pneumoniae account for the most,and the number of Fungi is the fewest.Drug resistance rate of gram-negative bacteria is higher than that of Gram-positive bacteria.Gram-negative bacteria has higher resistance to ampicillin,cefoperazone,ciprofloxacin,levofloxacin and eotrimoxazole.Gram-positive bacteria has higher resistance to penicillin,cefazolin and gentamicin.Conclusion To elderly paraplegic HAP patients,the main pathogenic flora is gram-negative bacterium which shows multiple resistances.Being familiar with the features of pathogens and their drug resistance will provide better guidance on early treatment and improve prognosis of elderly paraplegic HAP patients.

[Obiective] To summarize the research development of the relationship between the occurrence and development of common liver diseases and miRNAs by reading and analysing the literature published in recent 10 years. [Method] By literature retrieval, we consult the literature about miRNA and the clinical research of relevant liver diseases since 2003 and summarize the regulatory mechanism of miRNAs in liver diseases. [Result] miRNAs regulate the expression of target genes at the post-transcriptional level, and they are involved in many important biological processes. In recent years, we can find that miRNAs take part in the regulation of many liver disease-related genes, and the expression level in hepatocellular carcinoma, viral hepatitis, liver fibro-sis, cirrhosis, alcoholic and non-alcoholic fatty liver change in different levels. Part of the regulatory mechanism of miRNAs has been clearly identified, suggesting that miRNAs wil be used as new therapeutic targets for liver diseases. [Conclusion] The regulatory mechanisms of miRNAs in liver diseases make a big difference for the prevention and treatment of liver diseases. These findings provide some novel thoughts about the detection, study and treat-ment about relevant liver diseases. However, many questions are stil vague and unknown, such as the net of its expression and regulation, its biological functions, and the relationship with liver diseases, and al of them are needed to get further attention.

Neurofibromas are benign nerve sheath tumors that arise from the nonmyelinating Schwann cells. Generally, neurofibromas can be categorized into dermal and plexiform subtypes. The former subtype is usually associated with a lone peripheral nerve in the integumentary system, while plexiform tumors are associated with many nerve bundles and can originate internally. Rarely, the plexiform tumors can undergo malignant transformation. Neurofibromas are usually found in individuals with neurofibromatosis, which is an autosomal dominant disease. On occasion, an isolated neurofibroma can transpire without being associated with neurofibromatosis. Mostly, these solitary tumors tend to occur in the gastrointestinal system, and neurofibromas of the head and neck are not uncommon, but very rarely they have been reported to occur in the temporal fossa. In this report, we describe a case of a solitary neurofibroma arising from the temporal fossa.
